Miniature rose plant named Intersept

ABSTRACT

A new variety of miniature rose plant having red flowers produced on a good pot forcing plant also suitable for growing outdoors in gardens.

SUMMARY OF THE INVENTION

The present invention relates to a new and distinct variety of roseplant of the miniature rose class, which was originated by me bycrossing as the seed and pollen parents unnamed and unpatented seedlingsof my creation. The varietal denomination of the new variety is`Intersept`.

Among the novel characteristics possessed by this new variety whichdistinguishes it from its parent and all other varieties of which I amaware is its bright red flowers borne on a plant particularly suited forproduction of flowering pot plants and for growing in outdoor gardens.`Intersept` can be reproduced through propagation by cuttings, grafting,budding and micropropagation. Flowers of the new variety are longlasting on the plant. Asexual reproduction by budding, grafting andpropagation of cuttings of the new variety as performed in Hazerswoude,Holland, shows that the foregoing and other distinguishingcharacteristics come true to form and are established and transmittedthrough succeeding propagations.

BRIEF DESCRIPTION OF ILLUSTRATIONS

The accompanying illustrations show typical specimens of the vegetativegrowth and flowers of the new variety in different stages of developmentdepicted in color as nearly true as it is reasonably possible to makethe same in a color illustration of this character. Phenotypicexpression, including colors, may vary depending upon growingconditions, such as under different climate, soil, and cultivationconditions.

FIG. 1 is an illustration of a plant of the new variety of miniaturerose showing flowering and growth habit; and

FIG. 2 is an illustration showing details of the new miniature rosevariety.

DETAILED DESCRIPTION OF THE NEW VARIETY

The following is a detailed description of my new variety, with colorterminology in accordance with The Royal Horticulutral Society ColourChart (R.H.S.C.C.) and horticultural terminology in accordance withstandard terminology used in UPOV-approved horticultural guidelines. Theterminology used in color descriptions herein refers to plate numbers inthe aforementioned color chart.

Parentage: Seedling.

Seed parent.--Unnamed seedling.

Pollen parent.--Unnamed seedling.

Class: Miniature.

As can be seen in the accompanying illustrations, FIG. 1 shows onesample of flowering plant of `Intersept` depicting the pot plant habitof growth and flowering. Since flowering is nearly continuous, thefloriferous `Intersept` can remain attractively in bloom for longperiods when given proper care and culture.

The illustration in FIG. 2 shows details of the new variety "Intersept".In the illustration there is shown the top of a young shoot, 1; compoundthree, five and seven leaflet leaves, 2, 3, and 4, respectively; a stem,5; buds, 6 and 7; a flower, 8, about one-half open; and a flower 9,fully open. Also shown are flower stems 10, 11 and 12, with reproductiveorgans.

The following further horticultural observations were made of specimensgrown outdoors in Holland.

FLOWER

(4) Sepals.--Slightly longer than bud, simple to slightly foliated.

(5) Peduncle.--Length -- medium. Aspect -- straight. Strength -- erect.Color -- medium green.

B. Bloom: flower: Average size for miniature.

Viewed from above.--Irregularly rounded.

Viewed from side.--(a) Upper part of fully opened flower -- flat; (b)lower part of fully opened flower -- flattened convex.

(1) Size.--Average size when fully expanded -- about 3 to 4 cm.

(2) Borne.--Small clusters, 3 to 4 blooms, and singly.

(3) Form.--Ovoid to cupped at first, becoming flat; some outer petalsreflex and quill to points; inner petals roll under slightly.

(4) Petalage.--About 20 petals under normal conditions -- double.

(5) Color.--After sepals separate, near 45A to B; when sepals part andpetals being to unfurl, color of petal tops remain near 45A to B; petalsundersurface is similar near 45-45C. Open flowers show orange-yellowanthers and pollen. Coloring at point of petal attachment is near 57D.Overall tonality from a distance is bright red.

(6) Pedicle.--Few hairs or prickles.

(7) Fragrance.--Slight to none.

C. Petals:

(1) Texture.--Medium.

(2) Appearance.--Inside velvety and outside satiny.

(3) Form and size.--Small, obovate.

(4) Arrangement.--Regularly arranged, imbricated.

(5) Petaloids in center.--Several.

(6) Persistence.--Drop off cleanly.

(7) Lasting quality.--Long lasting quality on plant.

REPRODUCTIVE ORGANS

A. Stamens, filaments and anthers:

Arrangement and color.--Regularly arranged around styles; color offilaments -- pale yellow.

B. Pollen:

Color.--Yellow orange.

C. Styles: Stigma above mouth of receptacle, pale yellow green,generally not hairy.

D. Stigmas: Positioned slightly above anthers.

E. Hips: Small, pear-shaped.

PLANT

A. Form: Bushy.

B. Growth: Vigorous.

Average height.--about 30 cm.

Average spread.--about 20 cm.

C. Foliage: Compound 3, 5 and 7 leaflets.

(1) Size.--Medium for a miniature.

(2) Quantity.--Abundant.

(3) Color.--Foliage at time of first flowering -- light to medium green.

(4) Shape.--Oval, pointed.

(5) Texture.--Upper side has little or no gloss; underside is matte.

(6) Edge.--Serrate.

(7) Serration.--Ordinary, acumiante apices.

(8) Leaf stem.--Color -- medium green.

(9) Stipules.--Short, narrow, simple, medium to light green, distinctauricle.

(10) Leaflets.--Cross section -- slight concave, little or no undulationat margin; terminal leaflet -- very short, very narrow, obtuse base;petiole -- short.

D. Wood:

(1) New wood.--Color -- medium green, young shoots have little or noanthocyanin coloration -- green to green-bronze.

(2) Old wood.--Color -- medium green.

E. Prickles (thorns):

(1) Prickles.--Present, quantity (main stalk) -- ordinary. On lateralsfrom stack -- ordinary. Form -- straight. Shape of upper side --concave. Shape of lower side -- flat. Length -- medium ≦5 mm; few >5 mm.Color -- tan to pale pink Position -- irregular.
